Adhesive (chemical) anchors are used frequently in both new construction and repair/retrofit projects. Current design codes do not contain rational design procedures for these anchors. An experimental program was undertaken to determine the behavior of these anchors and to develop a rational procedure for their design. The experimental program described in this study involved 97 tensile tests of 6 adhesive products on the following types of 5/8-in. diameter threaded anchors; fully bonded single anchors; partially bonded single anchors; and fully bonded anchor pairs. A behavioral model based on an elastic formulation is developed and assessed. Design recommendations for single and multiple adhesive anchors are presented in the paper.
